' Application To all whom it may concern.'

Beit known that l, VERNON E. LA MASTER, a citizen of the UnitedStates, residing at Beardstown, in the county of Cass, State of lllinois, have invented certain new and useful Improvements in Automobile-Radiators; and l do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

. This invention relates to automobile radiators.

The object of the invention is to provide a simple arrangement for maintaining heat in a water circulating system of an automobile engine, so that the usual delay incident upon cranking a cold automobile engine will be avoided. ln carrying out the invention l have provided a heating element which is fed from the fuel supply of the automobile, and is so arranged that it may be kept in operation during that period when an automobile is standing still, either in the street or in a garage.

Vith the above objects in view, and such others relating to the details of construction, as may hereinafter appear, my inven tion will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure l is a section through an automobile radiator showing my invention applied thereto,

Fig. 2 is a section through the system,

Fig. 3 is a detail section of the burner element,

F ig. l is a transverse section through the radiator.

Referring more particularly to the drawings, l represents the usual automobile radiator which consists of the upper manifold or chamber 2 and the lower chamber or manifold 3, the latter being connected by means yof the usual spaced water tubes 4. Extending vertically through the bank of water tubes 4 is a conduit 5. @n lines which coincide with substantially the central portions of the chambers 2 and 3, the conduit 5 branches in both directionsin the arms 6 and 7. The extremities of the arms 6 and 7, near the corners of the radiator, are con- Speci'oation of Letters latent.

culation are provided, namely, onethrough the conduit 5 and the other through thearms and the vertical components. ln other words, one portion of the heated air will travel direct through the main conduit 5, and the other portion will divide, the parts traveling through the longer course including the arms and the side components. lt is believed the heat passed direct through the main conduit will be more intense and will move more rapidly than that which passes through the components. and t iis isdesirable because it will heat the water at the transverse center of the radiator to a higher degree than at its sides and therefore will set up a .circulation in the water as willv be clearly understood. The upper end of the conduit 5 vents through the top of the radiator, and the lower end thereof passes through the bottom of the radiator and terminates in a hood 9.

'llhe hood 9 lies inside of a. heater casing 10 within which is located a gasolene genera`.

tor burner ll preferably of the retort type, which may be kept in a burning state by means of a comparatively small quantity of gasolene which is' fed thereto through a pipe l2 which comes from the fuel supply tank not shown. T he generator burner ll is disposed directly below the hood 9, so that all of the heat therefrom will pass into the lower end of the conduit 5, and will be distributed in the manner above defined. rThe casing may have a door to give access to the heater, and the casing or the door may have openings to admit air.

'In order to restrict and hence to retard the flow of heat through the arms 7, baffles 13 are disposed at their points of union with the main conduit 5 as best seen in F ig. f2. As therein illustrated, these baffles are small plates converging upward toward the axis of the main conduit.

lt will be apparent from the foregoing description that l have provided a simple and effective means for maintaining a degree of heat in the water circulating system of an automobile, and that by the use of a gasolene generatorburner, the heat may be maintained for a long period at a slight expenditure of fuel. ln' fact, the device may be kept burning throughout the night in a garage, so as to prevent the freezing of the water system with consequent damage to the machine.

I' from the-rst and extending in tortuous courses upward vthroughthe radiator near its sides and top and united near the latter with said main conduit, as and forthe purpose described.

2. The combination with an automobile radiator, of a casingvvfor attachment to the bottom of the radiator and adapted to contain a heating unit, a hood above Said unit,

a main conduit leading from the hood straight upward through the radiator and open at its top, arms branched from the conduit and extending outward in the radiator near itsbottom, thence upward 'in vertical components, and thence inward in other arms near the top of the radiator and united with said conduit, and baflies at the juncture of the lower arms and conduit leaving the axisv of the latter open but restricting the flow of heat through said arms, as described. In testimony whereof, I aiix my signature in the presence of two witnesses.
